His tone seems exasperated, disengaged from your needs, and cold. Whether or not you should have emailed him numerous times is not really up for discussion - it is simply a manifestation of your attachment/transference experiences and as such it is the therapy work itself. If a therapist engages in email contact, they need to be able to manage their feelings around the potential intrusions and associated significant client need. His annoyance is thinly disguised. I hope your session goes well.
